... in these techniques. A more satisfactory. approach toward predicting the sedimentary environment is achieved with two cumulative probability curve techniques and with the regional and stratigraphic variations in single grain-size parameters. A lower foreshore to shallow marine sand bank environment is deduced...

... in deltaic and alluvial deposits can be added their presence in the shallow marine Late Jurassic Canyon Springs Sandstone in the southern Black Hills, South Dakota. Proposed origin for dish structures from antidunes or grain flow in the upper flow regime are not compatible with associated structures...

... orthoquartzitic sandstones with thinner siltstones and mudstones. The arenite member at the base of the Wit-Mfolozi section is attributed mainly to shallow marine deposition. The upper 5 m display features which are suggestive of a low tidal sandflat environment. These include reactivation structures, herringbone...

...ANTHONY G. DORÉ Abstract Interpretation of shallow seismic reflection profiles indicates a thick Permo-Triassic to Jurassic sequence, overlain in the west of the region by at least 400 m of upper Cretaceous. Both sequences are folded along E.–W., westerly-plunging axes. Cores obtained from an area...

... Group). The sediments appear to have been deposited in a shallow marine basin that was slightly displaced and then subsided rapidly as the dominantly submarine basalts of the Vandfaldsdalen and Mikis formations were erupted. Macro- and micro-fossils indicate that this basin was present by upper Albian...
